FRANK RYMAN, OF AVALON, PENNSYLVANIA.-

POWER-HAMMER.

SPECIFICATION forming part of Letters Patent No. 498,752, dated May25,0,.1893.

Application filed November l17, 1892.

To all whom it may concern.-

Beit known that I, FRANK RYMAN, acitizen ofthe United States, residingat Avalon, in the county of Allegheny and State of Pennsylvania, haveinvented certain new and useful Improvements in Oscillating Anvils forPower- Hamrners; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the artto which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to an improved power hammer, and more particularlyto that class having an anvil adapted to be oscillated, and consists incertain details of construction and combination of parts as will befully described hereinafter.

In the accompanying drawings, Figure 1 is a front elevation partly insection of my improved anvil for power hammers which is constructed inaccordance with my invention. Fig. 2 is a side elevation of the same.Fig. 3 is an enlarged front elevation of the die or hammer-block,showing a means of holding the same stationary.

To put my invention into practice I provide a frame 1, of a suitablesize and form of construction, and place the same on a foundation 12.Arranged at the front of this frame is an anvil 6, the lower extremityof which is placed in a recess formed in a stationary block 11, and theupper portion formedwith an opening 7, in which an eccentric is made tooperate. This eccentric 8 is adapted to give the anvil an oscillatingmovementand is mounted on a shaft 9, and operated by means ot a handcrank 10. Secured in the top ot this anvil 6, is a die 14 which may beremoved and replaced by another to correspond with the desired form ofthe work. Operating vertically abovethe anvil 6 is a hammer 3, having aremovable die 5, at the lower end, and an orifice 2O at the top for thelreception of one end of a lever 2. This 1e-` ver 2, is pivoted in theframe 1, and connected to a suitable power to give the same avertioalmovement, whereby the hammer 5o head 3, is elevated and dropped upon theSerial No. 452,317. (No model.)

die 14. An opening 15 formed horizontally through the frame 1, serves toletthe work pass through while being operated upon. By placing twoblocks 18 one at either side of the anvil 6, and bearing against lugs 19formed integral with the frame 1, the saidl anvil is held stationarywhich is desirable in some classes of work.

' In operation power is applied to the rear end of the lever 2, whichgives the hammera vertical movement. The iron or metal after beingheated is placed in the die 14, and by means of the crank 10 the anvil'6is moved sidewise, or oscillated back and forward,

which movement will flatten the iron.

By means of a machine constructed as described, aXle clips for vehicles,and other like fittings, are easily formed, and the apparatus may beused for many other purposes.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination, with a power-hammer, of an anvil having its lowerportion supported to permit of lateral movement and its upper portionprovided with an opening, and an eccentric working in said opening toimpart an oscillating movement to the anvil.

2. The combination, with a vertically movable power-hammer, of an anvilhaving its lower portion supported to permit of lateral movement and itsupper portion provided with an opening, an eccentric working in saidopening, and a crank forimpartingmotion to the eccentric wherebytooscillate the anvil.

3. The combination,with apower-hammer, of an anvil having its lowerportion supported to permit 0E lateral movement and its upper portionprovided with an opening, an eccentric working in said opening to impartan oscillatory movement to the anvil, and means for holding the anvilstationary with relation to the hammer.

In testimony that I claim the foregoing I hereunto afx my signature this24th day of September, A. D. 1892.
